DETACHABLE HANDLE FOR HAND-CARDS.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed October 12, 1912. Serial No. 725,375.

To all whom it may concern:

Be it known that I, HERBERT MIDGLEY, a

citizen of the United States, residing at Worcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Detachable Handle for Hand Cards, of which the following is a specification, reference being made therein to the accompanying drawings.

My present invention relates to handcards such as are employed for stripping or clearing fiber from the cylinders of carding engines, and for similar purposes; and consists in a detachable metal handle and the manner of combining the handle with the base or back-board of the card; the object of the invention being to provide a convenient and efiicient metal handle that can be readily attached to and detached from the cards; that will accommodate varying widths, and may be used on different card bases or backs; also to afford a handle device that is simple to assemble and attach, and that will hold in place rigidly and strongly and not be liable to become loose, nor to pull off from the card while in use.

Another object is to provide a handle construction for hand cards of the character described, wherein the metal handle may be manufactured as a separate article fro-m the ter become successively worn out in service. Another ob ect 1s to provide a handle that will afi'ord a good and secure grip, and will not slip in the hand; also that will prevent the back or base of the card from warping or straightening out of its original shape.

These objects I attain by means such as explained in the following detailed descrip tion, and illustrated in the drawings, wherein Figure 1 represents a top view of a hand card provided with a detachable handle mechanism illustrating my invention. Fig. 2 is a part side part sectional view of the same. Fig. 3 represents the forward edge of the back-board or base of the card, showing the under cut recesses therein into which the handle is secured. Fig. 4 is a fragmentary perspective view showing the recess in the rear edge of the card back. Fig. 5 is a bottom view of the sliding sleeve member separate from other parts. Fig. 6 is a front end View of the same, and Fig. 7 is a transverse section at line X X.

Referring to the drawings, the numeral 3 indicates the hand-card composed, in the instance shown, of a base or back 1 of fiberboard or other suitable stifi material, slightly curved transversely and longitudinally straight; a face-clothing 2 provided with carding teeth set therein; and metallic binding strip or frame 4 overlooking and uniting the edges of theback and face plies, and forming a rigid edge therefor. This manner of constructing the body of a handcard has been heretofore employed and is not in itself a feature of my present invention, and is claimed only as a hand card element in the combinations defined in the claims.

In accordance with my invention, for use with a hand-card and separable therefrom, I provide a metal handle, which is preferably constructed as shown. It comprises a brace or body member 5 having a forwardly eX- tending arm or bifurcated portion 6, the under side of which is adapted to seat against and support the back of the card, while the rear end of said brace is formed as a backwardly extended stem or screwthreaded shank 7. At its front end the brace is furnished with downward lugs or means 9, to interlock or engage with an under-cut der in the frame metal that fits the side of the brace-lug, alfording endwise support for the card within the handle.

A sleeve member 12 is arranged to slide upon the shank 7, and provided at its forward end with projecting horns or portions 13, having under inclined surfaces 14 that co-act with upwardly inclined surfaces 15 formed upon the body or brace 5.' Said sleeve is also formed with a transversely disposed beveled under lip 16 adapted for engagement with an under cut or beveled recess 17 formed in the rear edge of the back of the card. The rear part of the sleeve is best made cylindrical, and preferably has a portion of its surface knurled. A. nut 19 is arranged upon the screw-threaded shank, abutting against the end of the sleeve 12 and adapted for forcing the sleeve forward and clamping the back of the card firmly between the lugs 9 and the lip 16, when the nut is screwed up. At the same time the inclined surfaces 14: and 15, acting against each other, causes the brace 5 to press firmly against the outer curved surface of the card;

thereby holding the handle and card together in strong rigid connection. The nut 19 is best made slightly less in diameter than the end of the sleeve 12, and with a portion of its periphery checked or knurled, its sides being slabbed off for receiving a wrench, as indicated in Figs. 2 and 7.

20 indicates an internally threaded handle-grip member that screws onto the shank 7 and against the nut 19, serving as a check therefor, and as the hand-piece of the handle. The exterior of this hand-piece is best knurled or checked, as shown, to afford a sure hold thereon and prevent lts slipping from the hand of the operator while in use. The hand-grip piece 20 is best made with a hollow cylindrical end portion 21 that exf tends forward over the nut and telescopes with the end of the sleeve 12, thereby inclosing the nut and forming a close joint with the sleeve for excluding dirt from the interior. The rear end of the hand-piece is pref- 1 erably chambered, and a wooden or non-metallic plug 23 is firmly inserted therein,

while a hole or holes 24 are formed laterally through the metal shell affording facility for tacking on a leather strip (not shown) 5 wound about the end of the handle, to form an enlarged end, which is sometimes desired by some operators.

under side of the sleeve 12, and which serves for attachment of a loop or strap through which the hand or fingers may be inserted;

at three places on the edges of the card, thus affording firm lateral rigidity; while the under cut bevels' and vise-like grip upon the edges of the same draws the back up to the curved brace, thereby tending to hold the back in proper shape and prevent its warping or straightening out; furthermore the handle will not pull off from the back of the card.

member 20 and loosening the nut 19 upon the threaded shank 17, so as to let the sleeve 12 move back thereon, thus disengaging the clamping lugs and releasing the back of the card therefrom. The new card can then be inserted and secured by a reverse of this op-' eration. The invention also permits of the handles and cards each being manufactured and sold as a separate article of manufacture, and assembled by the user as desired. Such method greatly facilitates the shipment and distribution, and effects ultimate economy in the production and use of handcards of this character.

What I claim and desire to secure by Letters Patent, is
